Inventor: SIMON DIETER DR RER NAT
IPC: C12P1/04
Filed: 1990-10-15
Abstract: Semi-continuous recovery of extracellular metabolites (I) by submerged culture of spore-forming bacteria comprises (1) batchwise growth of the culture in a fermenter until cell growth has reached the stationary phase and enzyme activity has reached 40-60% of the final value achieved in a comparable batch process, then (2) making numerous pulsed additions of substrate (pulse duration 0.1-2 hr) with intermediate substrate consumption/limitation stages (1-5 hr) such that spore-formation is suppressed.

It maintains conditions under which sporulation is inhibited and little, if any, cell growth occurs, although high biomass concncs. are retained. By preventing sporulation, the period over which (I) is produced is prolonged. Productivity is improved by over 100% and yields by over 30% compared with conventional batch methods.
